Mustang Exhaust H-Pipe and headers?

If you are getting shorty headers (Not Longtubes) I would save yourself the trouble and the price and just run an unequal lenght header.

When you go to buy a set of headers, look for ones that have a solid mounting flange. The headers that don't use a solid flange tend to warp and become "One time use" headers...

Might as well do long tubes vs equal length.
